Abstract

A disposable absorbent articles having breathable side panels. The disposable absorbent article preferably comprises a containment assembly including a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet. The absorbent core has a pair of opposing longitudinal edges, an inner surface and an outer surface. The backsheet has a garment-facing surface, a body-facing surface, a central region and an outer region. The backsheet preferably further includes at least three distinct zones, a pair of apertured zones comprising apertures and a non-apertured zone. The apertured zones preferably include at least a portion of the outer region of the backsheet and extend laterally outwardly form each of the longitudinal edges. The non-apertured zone preferably comprises the central region and is juxtaposed the outer surface of the absorbent core. The disposable absorbent article preferably further comprises a liquid and air pervious outer cover joined with the garment-facing surface of the backsheet to form a breathable laminate in the apertured zones. In preferred embodiments, a side panel extends laterally outwardly from each of the longitudinal edges of the absorbent core, each of the side panels comprising at least a portion of the laminate such that the side panels are breathable.

Claims

1. A disposable absorbent article having a front waist region, a rear waist region, a crotch region located between said front waist region and said rear waist region, a pair of opposed side edges, a first end edge located in said front waist region and a second end edge located in said rear waist region, the absorbent article comprising:

a containment assembly comprising an absorbent core having a pair of opposing longitudinal edges, an inner surface and an outer surface; and

a breathable laminate comprising a backsheet and an air pervious outer cover, said backsheet being positioned between said containment assembly and said air pervious outer cover, said backsheet comprising a formed film having a garment-facing surface, a body-facing surface, a central region, two apertured zones and a non-apertured zone;

said non-apertured zone comprising said central region and being juxtaposed said outer surface of said absorbent core;

said apertured zones comprising apertures and extending continuously laterally outwardly from said central region beyond said longitudinal edges of said absorbent core and continuously longitudinally from said end edge located in said front waist region through said crotch region to said end edge located in said rear waist region,

at least a portion of said garment-facing surface of said backsheet being joined with said outer cover juxtaposed at least said apertured zones.

2. The disposable absorbent article of claim 1 wherein said outer cover comprises an air pervious nonwoven web.

13. The disposable absorbent article of claim 1 wherein said backsheet comprises at least two members joined together.

14. A disposable absorbent article having a front waist region, a rear waist region, a crotch region located between said front waist region and said rear waist region, a periphery defined by a pair of opposed side edges, a first end edge located in said front waist region and a second end edge located in said rear waist region, the absorbent article comprising:

a containment assembly comprising a topsheet, a backsheet and an absorbent core disposed between said topsheet and said backsheet, said absorbent core having a pair of opposing longitudinal edges, an inner surface and an outer surface;

a pair of leg cuffs each having a proximal edge joined to said containment assembly laterally outboard of said opposing longitudinal edges and a distal edge;

said backsheet comprising a formed film and having a garment-facing surface, a body-facing surface, a central region;

said backsheet comprising at least three distinct zones, a non-apertured zone comprising said central region and being juxtaposed said outer surface of said absorbent core and a pair of apertured zones comprising apertures, one of said apertured zones extending laterally outwardly from each of said proximal edges of said leg cuffs to said periphery of the absorbent article;
